To all whom, it may concern:

Be it known that- L-Josnrrr E. FAWELL, residing at Pittsburgh, in thecounty of Allegheny and State of Pennsylvania, a citizen of the UnitedStates, have invented or discovered certain new and useful Improvementsin Rolling-Mills, of which improvements the following is aspecification.

It is now the general practice to construct mills embodying horizontaland vertical rolls with one or two pairs of vertical rolls. In bothcases the mills have been so constructed as to require for each pass ofthe article an adjustment of vertical rolls into or out of operativeposition. As for example, in operating mills having one pair of verticalrolls, the latter are moved to operative position when the article isbeing fed so as to pass first through the vertical rolls and thenthrough the horizontal rolls, but forthe return pass, the vertical rollsmust be moved to positions permitting the free passage of the article.

In operatin mills, having vertical rolls on each side of the horizontalrolls, one pair is adjusted to position to efi'ect edgewise reductionwhile the rolls of the other pair are adjusted to permit the freepassage of the article and when the article is returned through themill, the latter pair of vertical rolls is adjusted to reducing positionand the other is shifted to allow free passage of the article.

Both styles of mill are so constructed that for each and every pass thearticle must pass between the vertical rolls, whether one 01 two pairsof vertical rolls are employed, and also in one case the one pair ofvertical rolls and in the other case both pairs of vertica rolls must beadjusted for each and every pass. The invention herein described has forits object, a construction of mill in which provision is made forefi'ecting an edgewise reduction by a pair of vertical rolls, when thearticle is fed in one direction and its return movement through thehorizontal rolls will be at the one side of such "ertical rolls therebyavoiding any shiftin of the vertical rolls except as required %or progres'sive reduction. The invention is herein after more fully describedand claimed.

In the accompanying drawings forming a part of this specification,Figure 1 is a top plan view of a rolling mill embodying my improvement;Fig. 2 is a diagrammatic plan view showing the horizontal and a pair ofthe vertical rolls; and Fig. 8 is a view similar to Fig. 2,1showing apair of horizontal and two pairs of verticals arranged on oppositesides' of the horizontal rolls.

In the practice of the invention, the horizontal rolls 1 are mounted inthe usual or any suitable manner in the housings 2 and are operativelyconnected by spindles 3 and 4: and pinions 5 to a reversible prime mover6. The vertical rolls 7 have their upper and lower journal boxes somounted in suitable guides as to be capable of being adjusted by" theusual or any suitable mechanism, as indicated at 8 toward and from eachother.

It has heretofore been the practice to so construct the mill that thearticle must pass between the vertical rolls both for the forward andreturn passes. In the improved mill shown herein, the horizontal rollsare made of such a length that a pair of vertical rolls can be arrangedin operative position with relation to a portion of the horizontalrolls, while the article, on the return or back pass, the horizontalrolls being reversed, will be reduced by another portion of thehorizontal rolls and will pass entirely to one side of the verticalrolls. In a mill so constructed, the ver tical rolls are adjusted onlyto effect reduction and not to permit the return movement of the articleand hence as these rolls are rotated only in one direction anon-reversible prime mover 8 can be employed for driving them.

Ordinarily edgewise reduction will be necessary only after each secondpass between the horizontal rolls, but in case edging is required aftereach pass between the horizontal rolls, a pair of vertical rolls 7' maybe arranged in operative relation with a portion of the horizontal rollson one side of the latter, and another pair 7 b in operative relationwith another portion of the horizontal rolls, but on the opposite sideof the latter, as shown in Fig. 3. In such a con struction the verticalrolls will be out of line of the path of the article on the deliveryside of the respective passes between the horizontal rolls.

I claim herein as my invention:

1. A rolling mill having in combination a pair of horizontal rolls, areversible means for rotating such rolls, apair of vertical rolls andnon-reversible means for rotating the vertical rolls, the horizontalrolls being made of a length sufiiciently greater than the verticalrolls that portions of the h'ori zontal rolls at one side of thevertical rolls may be utilized as a return pass for the article.

2. A rolling mill having in combination'a pair of horizontal rolls andtwo pairs of vertical rolls arranged respectively on opposite sides ofthe horizontal rolls, the pairs of vertical rolls being so arrangedrelative to one anotl ier that the line of movement of an articlebetween the rolls of one pair of vertical rolls fii ilF betfone side ofthe line of movement of the article between the rolls 15 of the otherpair.

testimony whereof, I have hereunto set "my hand.
